“…31 The most prevalent morphology of the condyle in the axial view was anterior side concave/posterior side convex (37.9%), while the most unusual was biconcave (4.2%). These findings diverge from those of Yale et al 23 and Sülün et al, 16 who observed a higher prevalence of condyles with a convex anterior surface (biconvex). No association was observed between axial morphology and the position of the disc, in agreement with Raustia and Pyhtinen 32 and Solberg et al 33 Sülün et al 16 found an association between these variables, probably because they used a different sample (composed exclusively by symptomatic subjects) and a classification with a fewer number of categories, thus increasing the possibilities of statistical association.…”

“…10 Therefore, several authors have evaluated the morphologies of the condyle and articular disc and investigated the correlation between their morphology and disc displacement. 2,7,[9][10][11][12][13][14][15][16][17] MRI is considered the gold standard imaging modality for evaluating TMJ discs, as it produces images of excellent soft-tissue contrast. 10,[18][19][20] Moreover, it is a non-invasive examination that is free of ionizing radiation.…”

“…34 Nonetheless, some studies found a higher prevalence of anterior disc displacement in convex and rounded condyles, 15 and angled condyles. 16 Another study applied a more accurate method, in which condyle dimensions were defined by measures and found an association between narrower condyles in the anteroposterior and transverse directions with disc displacement. 35 Discrepancies in the results may be associated with different methodologies of evaluating condylar morphology.…”

Objectives:The aim was to evaluate the morphology of the temporomandibular joint's (TMJs) disc and condyle as well as its correlation with disc displacement, using MRI. Methods: 190 TMJs were retrospectively analysed. The condyle morphology of each TMJ was evaluated by two observers using both axial and coronal views, as were their disc morphology and displacement, using sagittal view. Condyle morphology was classified as flat, convex, angled or rounded in the coronal sections and as anterior side flat/posterior side convex, biconvex, anterior side concave/posterior side convex, flat or biconcave in the axial view. Disc morphology was determined as biconcave, biplanar, biconvex, hemiconvex or folded. x 2 , Fisher exact and Bonferroni correction tests were used to evaluate the data. ANOVA followed by post hoc Tukey's test was used to evaluate the interaction between age and disc displacement. Results: Anterior disc displacement with reduction; convex condyle morphology in the coronal view; anterior side concave/posterior side convex morphology in the axial view; and biconcave discs were found to be the most prevalent findings. An association was observed between disc morphology and disc displacement (p , 0.001). No correlation between condyle morphology and TMJ disc displacement was found (p 5 0.291 for axial and p 5 0.14 for coronal views). Conclusions:The results of this study suggest that TMJ disc morphology is associated with disc displacement.

“…Another explanation could be that the remodelling associated with disc displacement may result in a greater condylar angle. Reinforcing this explanation, Sülün et al 49 propose that the difference between the horizontal condylar inclination in patients with disc displacement and asymptomatic volunteers may be the result of remodelling or degeneration caused by the disorder.…”

The temporomandibular joint (TMJ) is part of the craniofacial complex and is made up of a large number of structures and elements, making its operation complex, so that small alterations can cause a wide variety of functional problems. 1. These problems are known as temporomandibular disorders (TMD), a generic term covering a group of musculoskeletal and neuromuscular conditions that affect the TMJ, the masticatory muscles and all associated tissues. 2,3 AbstractTemporomandibular joint disc displacement is common in the world's population and could be associated with bone and functional characteristics of the temporomandibular joint. The aim of these study was to analyse the association between temporomandibular joint disc position evaluated by magnetic resonance imaging (MRI) and the inclination of the mandibular condyle evaluated by computed tomography (CT).One hundred and seventy temporomandibular joints (TMJ) were retrospectively analysed. The temporomandibular disc position was evaluated by MRI and classified into three types: normal (N), disc displacement with reduction (DDWR) and disc displacement without reduction (DDWoR). The mandibular condyle measurements evaluated by CT included horizontal, sagittal and coronal inclination. ANOVA followed by post hoc Tukey's test was used to evaluate the interaction between condylar inclination and disc position. There was an association between disc position and the horizontal and sagittal condylar inclination (P < .05). There are statistically significant differences in the mean of horizontal and sagittal inclination of the mandibular condyle between the DDWoR and the other disc positions (P = .002 and P = .004). Disc position was not statistical associated with coronal inclination of condyle (P > .05). These results indicate that the inclination of the mandibular condyle may be different in TMJ with various disc position. A more medial horizontal inclination and a more posterior sagittal inclination of the mandibular condyle are associated with DDWoR. K E Y W O R D Scomputed tomography, magnetic resonance imaging, mandibular condyle, temporomandibular joint, temporomandibular joint disc |The TMD are a major health problem, affecting more than 50% of the world's population at some point in their lives and usually occurs in children, youth and adults of all ages and gender. 4,5 TMD can be classified into two major categories: temporomandibular joint disorders and masticatory muscle disorders. 2,3 Among the disorders of the TMJ are the alterations of the intra-articular mobility and the disorders of the disc-condyle complex. 2,6 Disorders of the disc-condyle complex consist of an abnormal position of the articular disc with respect to the mandibular condyle and the articular eminence. [7][8][9] Abnormal disc position or disc displacement has often been diagnosed in patients of diverse populations and can occur even in the growing population and is considered to be a condition that may worsen over time. 10,11 It has been observed that disc displacement of the TMJ is ab...

Objectives To predict temporomandibular joint (TMJ) anterior disc displacement with reduction (ADDWR) from condylar shape, position, and dimensions obtained from CBCT images. Methods This cross-sectional study was performed on 17 patients suffering from temporomandibular disorders diagnosed by history taking according to the chart of the American Association of orthodontists, clinical examination according to the Helkimo index and MRI. CBCT and MRI examinations were performed within one-week interval. Disc position, diagnosed by MRI was used as the gold standard. TMJs with posterior disc displacement or anterior disc displacement without reduction were excluded. Qualitative and quantitative analyses were performed on CBCT images to find the correlation between condylar variables and ADDWR. A logistic regression model was created to estimate ADDWR from condylar dimensions (height, width and depth). Results Condylar shape and condylar position in the glenoid fossa were significantly correlated with ADDWR (P < 0.05). Condylar width, height and depth were significantly smaller in condyles with ADDWR compared to condylar dimensions in normal disc position. Logistic regression analysis could be used to predict the probability of anterior disc displacement with reduction from condylar dimensions. Conclusion Condylar shape, position, and dimensions assessed by CBCT are significantly correlated with ADDWR of the TMJ. Substituting the values of condylar width, height and depth in the equation suggests the probability of ADDWR.
